New Redsn0w 0.9.10b3 - ( 02 January 2012 ) - iOS 5.0.1

A few days ago, @pod2g gave the untether to both the iPhone devteam and the chronic devteam.
We’ve put it into redsn0w 0.9.10 and PwnageTool, and the chronic
devteam put it into a Cydia package (the same set of exploits is in all
three).
Here are the basic steps for how to get it:

If you have one of those devices and are not on 5.0.1 yet, update now! The SHSH window is still open for 5.0.1 If you unlock via ultrasn0w or gevey, make sure you only get to 5.0.1 via a custom IPSW! See the guides at places like iClarified.com if you don’t know how. Once you’re at 5.0.1, use the latest redsn0w 0.9.10 to both jailbreak and untether.

If you’re already at 5.0.1 with a tethered jailbreak, you have two choices:
either run redsn0w 0.9.10 over your current jailbreak (deselect
“Install Cydia” if you do that), or install the Cydia package prepared
by the chronic devteam. The patches are the same regardless of which you choose.

Some of you are using a hybrid 5.0/5.0.1 configuration. If so, do
not attempt to install this untether over that setup! You will most
likely get into a reboot cycle. Do a sync and fresh restore to 5.0.1
then install the jailbreak + untether.
